CLEANER FOR FRUIT-JARS, 84.0.

SPECIFICATION forming part of Letters Patent No. 415,625, dated November19, 1889.

Application filed May 23, 1889. Serial No. 311,896. (No model.)

To all whom it may concern.-

Be it known that I, SANFORD WV. ERWIN, a citizenof the United States,and a resident of Mount Meridian, in the county of Putnam and State ofIndiana, have invented certain new and useful Improvements in Cleanersfor Fruit-Jars, 85c. and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, andshows a vertical section of a jar, with a front view of the cleaner.Fig. 2 is a perspective view of the cleaner.

The invention relates to devices for detaching or removing splinters orslivers which adhere to glass jars and other hollow glass articles asthey come from the factory; and it consists in the construction andnovel combination of the parts constituting the instrument, ashereinafter set forth, and pointed out in the appended claim.

In the embodiment of my invention I provide a length of spring metal,which is made rectangular in cross-section, so that it will have angularedges to a. At its middle portion the bar is bent in loop form toprovide a handle, as at b. The branches of the bar, twisted to form theshank portion 0, are from the lower end of the twisted portion eachformed into a series of loop-spirals d (l, lapping a little one aboveanother, as shown. These loops (1 d are therefore in two vertical rows,having the inner edges near each other. The spirals (l d are turnedoutward, and in consequence of the spiral bending the angular edges atthe outside of the loops are presented in a salient manner, so as toform scraping-edges adapted to readily detach the glass particles orsplinters from the neck portion of a jar when the instrument is turnedback and forth therein.

In order to provide for cleaning the inside wall of the vessel, eachbranch from the lowest spiral loop is bent outward to form a shoulderportion K, which is bent downward by a rounded curve, as at l, andthence extends downward to its terminal portion,which is bent inward andslightly upward, as at m, forming the bottom-cleaning portion. Theplanes of the branches B B of the instrument are slightly oblique, sothat each branch has one of its outer angular edges a little moredistant from the axial center than the other, thereby forming a salientangular edge to scrape the inner wall of the jar when the instrument isturned therein to detach the splinters.

The instrument can be introduced into the Vessel when the branches areclosed or sprung sufliciently past each other for the purpose, and whenintroduced they will spring outward to working position. ,The elasticityof the branches also allows the instrument to be easily withdrawn.

Having described this invention, what claim, and desire to secure byLetters atent, Is-

The instrument for detaching splinters from the interior of glassvessels, provided with the upper end loop, the intermediate series oftwisted loops, and the laterally-extended lower portions or branches,the latter portions, together with said intermediate twisted loops,having their angular or corner edges presented to and adapted to actupon said splinters, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
